As stated below, I just tried the install boot using sarge, and did not get the “kernel paging request” error. Perhaps this is because I got a different error. After finding the aboot.conf file on the CD image, I entered the command as follows:
>>>boot dak400 –fi /boot/vmlinuz –fl “ramdisk_size=16384 initrd=/boot/initrd.gz root=/dev/ram devfs=mount,dall”
(NOTES: I had to use “vmlinuz” because “linux” did not exist on the CD. I also could not find a “root.bin” for initrd to use, but aboot.conf referenced /boot/initrd.gz so I used it. I also used the ramdisk_size and devfs flags because I got the similar errors without using them. Without ramdisk_size, it simply gave a different address for the error. And devfs appeared to do nothing.)
Then I got this error:
VFS: Cannot open root device “” or 08:02 Please append correct “root=” boot option Kernel panic: VFS: Unable to mount root fs on 08:02
In my mind this means that it could not use /dev/ram to mount the root file system, though I do not know why. I will continue to try various parameter to see if I can get it to work, but I suspect I will need an expert to point me in the right direction.

Helge,
Thank you ever so much for helping! I have been struggling now for a week. Here is the extent I can record of the paging error. There are two screen of data that scrolls by before I can write it down. If we need that too, you will have to show me how to stop the screen from scrolling (I tried ctrl-s and even the [pause] key but neither stops the screen.

Helge – I saw on some messages that some people with Alpha boxes had this paging problem when they were using kernel 2.2 and 2.4. I noted that one person reported the problem did not occur when they used kernel 2.6. I have downloaded sarge (which I believe uses 2.6) and I plan to try that later today. Thanks again for your help. Jim

Are you using the woody boot floppies installer or the new debian installer?
I have been using Woody CD images.

Can you try to copy down this paging error? This seems the real cause of the problem.
Will do…

The documentation is just giving examples from "normal" operation. Depending on the name of the kernel to boot, this line my be different. But Yes you are right, it looks a little strange. Can you try (at the aboot prompt):
b /boot/linux root=/dev/ram initrd=boot/root.bin I used this just now to recreate the paging error I am documenting.

During the initial install a ramdrive is used, so this setting is probably correct. OK

There should be a file /boot/root.bin which contains an INITial RamDrive, i.e. a small container holding lots of drivers and other modules. Thanks.

This should not be needed. I don't know if it is even considered at all. I will ignore.

I think this was used in the past when you actually applied floppy disks. I don't think it is in use today still. I will ignore.

Well, the problem is a)that people usually get M$ preinstalled and b)you've (unfortunately) run into a strange install error and c)alpha are different considering booting (though when running they are pretty similar to i386 linux), so there's an extra hurdle here for the newcomer. Agreed.
Please try to post the exact error message about this paging and then we can better help you.
